Topic of the Week - Hatching Eggs

[DsLittleDarling]

When you crack one open look for the formation of the blastodisc and bullseye. These are chicken, but same concept

I really didn't want to Crack it open. Just wanted an easy way to find out without damaging the egg.

Unfortunately the only way to determine fertility without opening the egg is by incubating it and candling it after approximately 7 days to check for development. Before day 7 it's hard to tell for sure, unless you have a pale enough egg shell and a very strong light for candling. I usually candle again at day 10, before discarding clear eggs.
